RadiAnt DICOM Viewer


Opening DICOM studies from CD/DVD/BluRay disks and local or network folders.

Searching and downloading DICOM studies from PACS locations (servers, workstations, modalities).

Storing DICOM studies in a local database.

A simple and intuitive interface with full-screen mode.

Multi-touch support for Windows 8/8.1/10 enabled devices.

Excellent performance – 64-bit version available, multi-core and multi-processor support, asynchronous reading (you can browse images while they are being opened), advanced memory management system which facilitates concurrent opening of studies with thousands of images. All provided within a compact application (installer size is just around 7MB).

Native ARM 64-bit version for new generation of devices (e.g., Surface Pro X).

Image operations:

Fluid zooming and panning.

Brightness and contrast adjustment, and negative mode.

Preset window settings for Computed Tomography (lung, bone, etc.).

Rotations (90 and 180 degrees), and flips (horizontal and vertical).

Image filters: sharpen, smooth, edge, emboss.

Regions of Interest (ROIs):

Measurement of segment length.

Measurement of mean, minimum and maximum parameter value (e.g. density in Hounsfield Units in Computed Tomography, SUVbw in PET) within circle/ellipse and its area.

Measurement of area and perimeter of closed polygon.

Measurement of open polygon length.

Measurement of angle value (normal and Cobb angle).

Measurement of deviation.

Arrow tool for annotations.

Pen tool for freehand drawing.

Browsing of several series concurrently in multiple panels with automatic synchronization between series with images acquired in the same plane (e.g. Computed Tomography series before and after contrast media administration) or manual synchronization between series from different studies with similar patient orientation and cross reference lines in series with different image planes (e.g. Magnetic Resonance study).

3D cursor tool.

Display of dynamic sequences/series (CINE) with adjustment of frames per second.

2D (orthogonal) Multi-planar Reconstruction (2D MPR).

3D (oblique) Multi-planar Reconstruction (3D MPR) with MIP (maximum intensity projection), MinIP (minimum intensity projection) and Avg (average) modes.

3D Volume Rendering (VR).

3D snapshots for saving and restoring 3D VR views.

Export of 3D models to STL files.

Creation of quick movies (simple rotations) and advanced 3D snapshot-based videos with volume-rendered objects.

GPU acceleration for 3D VR and 3D MPR views (for Nvidia GPUs).

Fusion of series with different modalities (e.g. PET-CT) or with different protocols (e.g. MR T1/T2 – DWI).

Time-intensity curves (TIC, e.g. for Breast MRI).

Support for DICOM overlays (annotations or graphic overlays included in the file).

Export of DICOM images to JPEG and BMP picture formats and DICOM series/sequences to movies in WMV or MP4 formats.

Display DICOM file structure with searchable DICOM tags, their descriptions and values.
